A pneumatic sensing device is presented which automatically senses the motion of a ball falling into a can. A sensing arm protrudes into the pathway of the dropping ball. When the ball hits one end of the arm, the other end of the arm rotates upward and closes off an exhaust port, creating a back pressure in a proximity switch. The proximity switch then sends a pneumatic signal to a four-way valve that allows the now filled can to move on to the next work station. Also presented is a method of using the sensing arm which uses a regulator and indicator to...
A pneumatic sensing device comprising: (a) a base having a drop tube receiving hole therein for receiving the top of a drop tube; (b) a drop tube having a cylindrical inner shaft, the top of said drop tube being attached to said base at said receiving hole and the bottom of said drop tube having a first slot therein; (c) an essentially L-shaped sensor bracket perpendicularly attached to the bottom of said base, the long leg of said bracket having a proximity switch port therein and the short leg of said bracket having a sensor arm pivotably attached ther...
